Crystal growth and thermoelectric properties of CaMn0.98Nb 0.02O3-δ
(Elsevier, 2013-05-24)
Thermoelectric CaMn0.98Nb0.02O3−δ single crystals were grown from sintered polycrystalline material using the traveling-solvent floating zone (TSFZ) method. The floating-zone furnace was operated at overpressure using an ...
Multiple interfaces in diffusional phase transitions in binary mesogen-nonmesogen mixtures undergoing metastable phase separations
(American Physical Society, 2012-07)
Theory and simulations of simultaneous chemical demixing and phase ordering are performed for a mixed order parameter system with an isotropic-isotropic (I-I) phase separation that is metastable with respect to an ...
Broad Geographic and Host Distribution of Apis mellifera Filamentous Virus in South American Native Bees
(Research Inst Pomology Floriculture, 2019-12)
Apis mellifera filamentous virus (AmFV) is a large double stranded DNA virus of honey bees and its prevalence and relationship with other parasites is poorly known. Samples consisted of fifty-one adult bees belonging to ...

Streptonigrin induces delayed chromosomal instability involving interstitial telomeric sequences in Chinese hamster ovary cells
(Elsevier Science, 2012-08-30)
We analyzed the induction of chromosomal aberrations in Chinese hamster ovary (CHO) cells exposed to the radiomimetic compound streptonigrin (SN), in order to determine whether interstitial telomeric sequences (ITSs) are ...
The key role of electrostatic interactions in the induced folding in RNA recognition by DCL1-A
(Royal Society of Chemistry, 2018-03)
The intrinsically disordered protein domain DCL1-A is the first report of a complete double stranded RNA binding domain folding upon binding. DCL1-A recognizes the dsRNA by acquiring a well-folded structure after engagement ...
Impaired male fertility and abnormal epididymal epithelium differentiation in mice lacking CRISP1 and CRISP4
(Nature Publishing Group, 2018-12)
Epididymal Cysteine Rich Secretory Proteins 1 and 4 (CRISP1 and CRISP4) associate with sperm during maturation and play different roles in fertilization. However, males lacking each of these molecules individually are ...
